Useful Information

Description and Purpose:

Listed as Part number: 22902634, this Genuine GM Diesel Emissions Fluid (DEF) Supply Pump Module is new to regulate the complex emission treatment systems of your Chevrolet and GMC diesel vehicles. It acts as the pressurized core for the DEF assembly, moving fluid from the reservoir to the exhaust stream to neutralize nitrogen oxides. Tailored for the Savana, Sierra, Express, and Silverado series—as well as the diesel Cruze—it ensures these workhorses maintain the precise flow rates required for their catalytic reduction systems. Interchange part numbers: 22783126, 22872119

Why Replacement is Important:

A failed pump often leads to "limp mode" or severe speed restrictions to enforce environmental compliance. Swapping in this module is critical to clear exhaust-related fault codes and restore the high-pressure fluid delivery required for normal, unrestricted driving.

Impact on Vehicle Performance:

Fitting this unit ensures your truck or sedan maintains its full power output and emissions legality. It preserves the heavy-duty reliability and fuel efficiency expected from these diesel-powered Chevrolet and GMC platforms, keeping them ready for the toughest tasks.

Manufacturer Information:

General Motors® applies advanced engineering and quality standards to provide parts that ensure precise fit, reliable functionality, and long-term durability.
